Summer Crush on Secret Path

Body text at this size
And the smaller size most interfaces actually use for paragraphs — the size that decides whether a pair is usable.
Caption text, which almost nothing passes.
WCAG 2.1
3.69:1
Large text only
Not AAA (7:1). Swapping the two colours gives the same number — the ratio does not know which is the text.
APCA
Lc -58.1
Clears Lc 45 — large or heavy display text.
Light text on a darker ground — the negative sign is the polarity.
Colour difference
ΔE00 38.6
different colours
Above 10 — related only in the sense that both are colours.
What the text colour has to become
#ffeef1 is the nearest colour of the same hue that passes AA on #737054, at 4.50:1. Only the lightness moved, and some chroma was given up to stay inside sRGB — which is the point: your colour stays recognisably your colour.
And to someone missing a cone
protanopia
Ratio 3.60:1, ΔE00 34.6.
deuteranopia
Ratio 3.74:1, ΔE00 34.5.
tritanopia
Ratio 3.71:1, ΔE00 36.5.
The weakest of the three is deuteranopia, where the two are ΔE00 34.5 apart against 38.6 for a trichromat — still clearly two colours.
